IMPROVEMENT IN SAWING-MACHINES.V

Specification forming part of Letters Patent No. 53,453, dated March 27,1866.

To all whom it may concern.:

Be it known that I, JOSEPH KUNZ, of Bay City, in the county of Bay andState of Michigan, have invented a new and Improved Hand l/Vood-Saw; andI do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference .bein g had to the accompanying drawing,forming part of this specification.

The present invention consists in hanging one of the ordinary handsawsin such a Inailner Within any suitable supporting-frame that it can beoperated with facility and ease and with but little labor compared withthe usual way now practiced for sawing wood used for household purposes,as will be obvious from the following` detail description, referencebeing had to the gure of the accompanying plate, which is a perspectiveview ot' my invention, showing it in use.

a a in the drawing represent an ordinary wood-handsaw, consisting of asaw-blade, l), hung within a frame, c, made of the usual construction.This frainec is hung, by its end d, to and between the lower ends of theside pieces, ff, of a vertical swinging lever-frame, g, hung, byitscross-piece L, at its upper end to and between the side pieces, Z l,of the supporting standard or frame m, having attached to it, at anangle thereto, another frame, n, which, when spread open therefrom,forms a sufficient base for the whole machine to rest upon. These framesm and n are strengthened by crossbracesoo at suitable points, and on theframe m, at the proper points thereot' to be in line with the swing ofthe saw-blade frame, are supports 19 p, across which the logs of wood tobe sawed are placed, as plainly shown in the drawing, and there held inplace bythenotched lever-bar q, hung` to the arm fr of one side of theframe m, and interlocking with the stud or pin s of one of the supportsp. At or near the upper end of the swinging lever to which the saw-bladeframe is hung is attached a box or receptacle, t, in which it isintended to place stones or other heavy material, so as to aid theforward movement ot' the saw-blade through the log of wood being sawed,as is obvious without further explanation.

The operation of my improved wood-handsaw is apparent from the abovedescription ot' its arrangement and from the illustration thereof shownin the accompanying plate, and therefore no particular explanation of itis necessary herein. Y

The point at which the saw-blade frame is hung to the swinging lever canbe changed at pleasure, according as may be desired.

I claim as new and desire to secure by Letters PatentrIhe arrangement ofthe saw c, adjustably pivotcd to the swinging weighted frame g, whichvibrates upon pivots in the supportingframe m n, substantially asdescribed and represented.

The above specication of my invention signed by me this 28th day ofSeptember, 1865.

JOSEPH KUNZ.
